The invention relates to a multi-layer three-dimensional automatic moving seedbed system. The system comprises a cultivation unit (A) and a moving unit (B). The cultivation unit (A) comprises single seedbeds (C) and driving devices (D). The moving unit (B) comprises a lifting table device (E), a chain wheel mechanism (F) and a wheel train mechanism (G), the moving unit (B) is driven by the wheel train mechanism (G) to move, the lifting table device (E) is driven by the chain wheel mechanism (F) to conduct lifting motion and stops at a designated position under the effect of a sensing positioning device, and the lifting table device (E) is provided with a first-stage pushing assembly and a second-stage pushing assembly and can transfer and carry the single seedbeds (C) to the designated position. By means of the system, optimal management of large-scale greenhouse production is achieved; when applied to fast spatial delivery and layout of seedbeds, the system solves the logistics problem in large-scale greenhouse production management, relieves the labor intensity of management staff, increases the utilization rate of greenhouse space per unit area and reduces the seedling culture cost.

The invention discloses a control system and method for a central air conditioning of a nuclear power plant, and solves the technical problems that the current central air conditioning is poor in energy-saving control management effect, the system object of control management is incomprehensive, and the control management interface is not visual enough. The control system comprises a data acquisition module, used for acquiring equipment operation data from an air conditioning water system and an air conditioning terminal system; a central control module, used for generating the corrected equipment operation data based on the environmental temperature and humidity, an air conditioning load dynamic prediction model and the acquired equipment operation data; a field control module, used for controlling the air conditioning water system and the air conditioning terminal system to operate based on the corrected equipment operation data; and a terminal display module, used for displaying and outputting the operation parameters, performance curves and images of equipment in the air conditioning water system and the air conditioning end system. According to the invention, the visualization operation of the control management interface is realized, comprehensive control and management are conducted on the central air conditioning system, the control accuracy of the air conditioning system is improved, and the effects of energy efficiency and cost reduction are achieved.
